Support is limited to customers who have already adopted these products. The μPC4572MF-DAA is a dual wide band, ultra low noise operational amplifier designed for low supply voltage operation of +4 V to +14 V single supply and ±2 V to ±7 V split supplies. Using high hFE PNP transistors for the input circuit, Input bias current and input equivalent noise are better than conventional wide band operational amplifier. The μPC4572 MF-DAA is an excellent choice for preamplifiers and active filters in audio, instrumentation, and communication circuit.
